1 Claim.

The present invention relates to improvements in windows and has reference more particularly to certain improvements in awning type windows.

This application is a divisional application of my application Serial No. 545,279, filed July 17, 1944, for improvements in Awning Type Windows, now Patent No. 2,486,407, November 1, 1949.

One of the important objects of the present invention resides in the provision of an awning type window, wherein means is provided for automatically locking the swinging sashes when the latter are in a fully closed position.

Another important object is to provide an awning type window embodying a plurality of vertically swinging sashes and a sliding actuating bar therefor, wherein interengaging means are carried by the sliding bar and one of the sashes for automatically locking the latter when the same is in a fully closed position.

A further object is to provide an awning type window embodying a plurality of vertically swinging sashes and a sliding actuating bar therefor and wherein one of the sashes is mounted for delayed opening, wherein interengaging means is associated with the sliding actuating bar and the delayed opening sash for automatically locking the latter when the same is in a fully closed position.

Other objects and advantages will become apparent during the course of the following description when taken in conjunction with the accompanying drawings.

In the accompanying drawings forming a part of this specification and in which corresponding numerals designate corresponding parts throughout the several views:

Figure 1 is an elevational view of a wooden window frame showing the awning type window mounted therein, with the window sashes illustrated in their fully closed and locked position.

Figure 2 is a vertical sectional view through the wooden window frame and the swinging sashes showing the latter in their fully closed and locked position and showing the interengaging means on the sliding actuating bar and the delayed opening sash in elevation.

Figure 3 is a view similar to Figure 2 showing the upper two sashes in a partly opened position while the lower delayed opening sash is still in its closed position, but unlocked.

Figure 4` is a similar sectional view showing the position of the swinging sashes when in their fully opened position.

Figure 5 is a perspective view of the locking means employed for securing the delayed opening sash in its closed position, the parts being shown disengaged.

Figure 6 is a sectional view taken approximately on the line B-B of Figure 2.

Figure 7 is a view similar to Figure 2 showing a modification of the invention as associated with a metal frame and metal window sashes.

Figure 8 is a view taken at right angles to Figure 7 showing the sliding actuating bar in elevation.

Figure 9 is a sectional view taken approximately on the line 9-9 of Figure 7.

Figure 10 is a transverse section taken on the line IIJ-IU of Figure 7, and

Figure 11 is a fragmentary perspectiveview of the locking means employed for the lower sash of the modification.

With reference more particularly to Figures 1 to 6, inclusive, there is disclosed an awning type window as associated with a wooden window frame, the latter being designated by the numeral I.

In the present instance, three sashes 2, 3 and 4, respectively, are employed.

Mounted for vertical slidable movement in a suitable guide channel 5 formed in each side of the window frame I is the metal actuating bar 6. There are two of such bars, one in each side of the window frame for cooperation with the respective ends of the several sashes.

Plate-like members l are disposed across the slidable actuating bar 6 and are secured to the frame I by suitable fasteners 8. These platelike members not only serve to retain the actuating bar in its channel, but also provide a means for securing one portion of the hinge unit that is associated at the respective sides of each sash.

Each hinge unit includes a link 9 that is pivotally connected `at its lower end, as at It to the respective plate-like member. The upper end of the link 9 is pivotally connected to the leg member II that is iixedly secured to the side edge of each sash. These members II constitute the sole means for supporting the sashes. Each leg member I I is formed with an offset arm portion l2 at its upper end. Y

The leg members that are associated with the uppermost sash 2 have their offset arm portions pivotally connected to the upper portions of the sliding actuating bars as indicated at I3.

The hinge unit that is associated with the central sash 3 is denoted generally by the numeral I4, and is more fully described in my copending application, Serial No. 545,279, now Patent No. 2,486,407, issued Novemberl, 1949.- j

The hinge unit that is associated with the lower sash 4 and the sliding actuating bar is denoted generally by the numeral I5 and is likewise fully described in detail in my aforesaid patent.

As clearly set forth in my copending application, Serial No. 545,279, now Patent No. 2,486,407, issued November l, 1949, the hinge unit construction as associated with the lower sash provides for the delayed opening of the lower sash.

The central or intermediate sash 3 is employed to constitute the operator for opening and closing the several sashes, although I do not wish to limit myself to this arrangement as the top sash may serve as the operator or an entirely independentoperator may be to effect the operation of the actuating bar.

A handle I6 is associated with the lower rail of the central opening sash 3 and this handle may also serve as a closure for cooperation with a suitable keeper I'I carried by the top rail of the lower sash 4 for locking these two sashes together when the sashes are in a fully closed position.

The means for locking the upper sash in its fully closed position is shown generally at I8 and the structural features embodied in the locking means for the upper sash is specically described and disclosed in my previously mentioned patent.

For the purpose of locking the lower sash 4 in its fully closed position, I provide the locking means shown in Figure 5 of the drawings.

This locking means includes a plate-like bracket I9 that is secured on the face of the lower end portion of the sliding actuating bar 5 by suitable fastener screws 20.

An offset hook portion 2| extends from this bracket I9, the open end of this hook facing upwardly.

The other part of this locking means for the lower sash 4 comprises' an angular bracket 22 that is secured on the lower sash 4. A lug 23 is arranged on the projecting side of the angular bracket 22 and the manner in which the hook portion 2| coacts with the lug 23 will be presently described.

With the parts 4disposed in the position shown in Figure 2, all of the vertically swinging sashes are locked in their fully closed position and the actuating bar is in its uppermost position in its guides. When the parts are in this position, the offset hook 2| will be in interlocking engagement with the lug 23. When it is desired to open the window, the handle I6 is iirst swung out of locking engagement with the keeper I1. Then the central sash is pushed outwardly.

This will cause the hinge units associated with the upper and intermediate sashes to move the actuating bar downwardly. During the downward movement of the bar 6 the locking means for the top sash will be released and also the hook 2| will move downwardly out of engagement with the lug 23.

As fully explained in my application, Serial No; 545,279, now Patent No. 2,486,407, issued November l, 1949, the upper and intermediate sashes operate simultaneously while the lower sash has a delayed opening and does not start to moveto an open position until the other two sashes have already been moved to an open position. Further, when the sashes are returned to a closed position, the lower sash will assume its fully closed position ahead of the other two sashes. Thus, the lower sash opens last and closes nrst.

The locking means for the upper sash will be brought into operation as the upper sash approaches its fully closed position, while the locking means for the delayed opening sash is brought into operation upon the further upward movement of the sliding bar, after the delayed opening sash is in its fully closed position.

Attention is now directed toigures '7 to 11, inclusive, wherein I have shown the invention as associated with a metal window frame and wherein metal sashes are employed. However, the principles of operation are the same.

In this form, the channeled metal window frame is designated by the numeral 25 and the metal frames of the sashes are designated at 26, 21 and 28, respectively.

Mounted for vertical sliding movement in the channeled metal frame 25 is the actuating bar 2S. This bar is formed with longitudinal slots 30, through which extend the pivot forming screws 3| that are threaded into the base portion of the channel shaped frame 25.

The hinge unit for the upper metal sash 26 is denoted generally by the numeral 32 and is described in detail in my aforementioned patent.

Ihe hinge unit that is associated with the intermediate sash 2'I is denoted generally by the numeral 33, and this hinge unit is likewise described in detail in my above referred to patent.

The hinge unit forthe lower sash 28 is denoted generally by the numeral 3d and this hinge unit is also speciiically described in the said patent.

An automatic locking means designated generally by the numeral 35 is provided for locking the upper sash in its fully closed position. This lock is identical with the lock unit I8 employedv for securing the upper sash of the wooden frame and sash structure.

For the purpose of locking the lower sash in its fully closed position, I provide an ear portion 36 that is struck out from the lower end portion of the slidable actuating bar 25 and is adapted to have engagement with the laterally extending nger 37 that projects from the lower sash 28.

The metal sashes are actuated in the manner as fully described in my copending application and also operate in the same manner as the wooden sashes. The upper and intermediate sashes will swing Voutwardly to a partially Yopen position while the lower sash still remains in its closed position.

Further downward movement of the actuatingV bar 26 will effect a delayed opening of the lower sash and this after the ear 35 has been moved downwardly away from the finger 3l.

When the sashes are returned to their fully closed position, the upward movement of the actuating bar will cause the locking means 35'to eiect an automatic locking of the upper sash while the ear 35 will be brought into engagementV behind the nger 3l' to lock the lower sash 28V in its fully closed position.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim. Y

Having thus described my invention, What'I claim is:

A fastener for locking the lowermost sash of a delayed opening multiple sash window in its closed position, wherein the sashes are mounted for swinging movement on horizontal pivots to4 open and closed positions in ai delayed manner by the vertical sliding movement of an actuating bar responsive to the swinging movement of one of said sashes other than the lowermost sash, said fastener comprising a latch member carried by the lower end of the vertically sliding actuating bar, said latch member comprising'a bracket `fixedly attached to the side face of the actuating bar, an oiset portion on the outer edge portion of said last mentioned bracket, a forwardly extending hook portion extending from the oiset portion, said hook portion having a notch extending downwardly from its upper edge to entirely receive a laterally projecting lug of a keeper unit, adapted to be attached to the lowermost sash, when the lowermost sash is in its fully closed position and the actuating bar is in its fully raised position responsive to the swinging movement of said one of said sashes.
